5.FAQ of Steel

We have organized several common questions for our clients，may help you sincerely：

1.How about your company？

A world class manufacturer & supplier of castings forging in carbon steel and alloy steel，is one of the large-scale professional investment casting production bases in China,consisting of both casting foundry forging and machining factory. Annually more than 8000 tons Precision casting and forging parts are exported to markets in Europe,America and Japan. OEM casting and forging service available according to customer’s requirements.

2.How to guarantee the quality of the products？

We have established the international advanced quality management system，every link from raw material to final product we have strict quality test；We resolutely put an end to unqualified products flowing into the market. At the same time, we will provide necessary follow-up service assurance.

3. How long can we receive the product after purchase?

Usually within thirty working days after receiving buyer’s advance payment or LC. We will arrange the factory manufacturing as soon as possible. The cargo readiness usually takes 15-25 days, but the shipment will depend on the vessel situation.

Q: Rock wool sandwich board Yanmian generally what brand, quality Zeyang?: We are all with a small factory rock wool, we do not know the manufacturers, but this thing is too much pollution

Q: Suzhou Yanmian sandwich board which is good?: It is recommended to consider Suzhou Fu new purification equipment Technology Co., Ltd., the company is specialized in the purification equipment R & D and production, purification engineering design, purification engineering construction, purification project maintenance clean room vacuum cleaner, laminar flow hood FFU, clean shed and electrostatic products sales Comprehensive technical services of high-tech enterprises. It can provide professional air purification system engineering design for air electronics, biomedical, hospital operating room, fiber optic cable, food and beverage, precision instrument, semiconductor and new material application, air purification system engineering, air purification system engineering inspection and air Purification system engineering and technical services; according to the customer's actual requirements and the actual needs of the design, manufacture, installation of clean room systems and equipment. So you can consider buying and cooperating.

Q: Flammable and toxic "" "", how long life?: Some polyurethane foam, some polystyrene foam. Non-toxic Flammable or not depends on the production of the time there is no plus flame retardant, the general GB is required B1 level, and non-flammable. Life expectancy, three to five years can certainly use = =

Q: Pressure plate composite insulation board and the difference between the sandwich panels, the price difference is large? What kind of geng good for steel structure plant design?: Composite insulation board is installed on the ground, the following layer of the board, the middle is the insulation cotton, the installation of a little trouble, the above is a layer of board. Sandwich panels are machined in the workshop of the plate, easy to install. The price difference between the two is not great. Steel plant should be based on the use of choice, sandwich panels and composite are useful. The composite board is better, but the price is also slightly more expensive.

Q: Color steel sandwich panels can be used for many years: If it is GB double-sided 0.45MM Baosteel foam 16KG / M, then 25 years certainly no problem

Q: Span 13 meters of the roof beam how to do the roof with 75mm foam sandwich board does not consider the wind load (indoor): Normal concrete beam span of not more than 5 meters, or the volume of the beam to do very exaggerated. So use a lightweight architecture It is understood that foreign general steel truss girder, but also useful wood beams under the steel truss.

Q: What are the key notes when buying a rock wool sandwich panel?: There are four key factors: 1. Look at the use of construction: long-term construction or plant application of high quality (rock wool density is equal to 120kg / m3, the outer steel thickness is equal to 0.7mm, thickness of 100mm or more) of the rock wool sandwich panels, because the simple rock Cotton sandwich board after the installation of the surface easy to arch, bubble 2. Flatness: the requirements of the facade of the high demand, the use of mirror flat cotton wool sandwich panels, mirror flat cotton wool sandwich panels than the production of ripples difficult 3. Fire resistance: rock wool board production process should pay attention to the mouth and the mother of the filler, filled with rock wool board fire performance, filled with polyurethane and other materials, poor fire performance 4. Gongkou and the mother after the joint, the horizontal joints at the level of high and low error, high-quality quality rock wool board error is very small, low-end products will be interested in the horizontal slit to 10mm desalination level difference.

Q: Share what is color steel sandwich panels, what are the characteristics and applications: Sandwich panels, composed of two layers of metal panels (or other material panels) and directly in the middle of the panel foam, mature molding of the polymer core insulation composition, easy to install, light and efficient. Filling system is also used to close the molecular structure, you can put an end to the condensation of water vapor. Sandwich panels are a common product in the current building materials, not only good flame retardant and environmentally friendly Sandwich board English name: laminboard Sandwich panel products are composed of two layers of metal panels (or other material panels) and directly in the middle of the panel foam, mature molding of the composition of the polymer core insulation. These sandwich panels are easy to install, lightweight and efficient. Filling system is also used to close the molecular structure, you can put an end to the condensation of water vapor. [1] The formation of the outer steel plate takes full account of the structural and strength requirements, and take into account the aesthetic, the inner layer of the formation of flat to meet the needs.

Q: Caigang sandwich panel roof can be covered with oil felt leakproof?: Can not, because the shop linoleum waterproof need to heat, and color steel inside the bubble, heating to melt!

Q: Lightweight insulation color steel sandwich board clip what the core: Color steel plate sandwich material is divided into foam color steel plate (chemical name for the polystyrene color plate), rock wool color plate, polyurethane color plate, paper honeycomb sandwich panels, glass wool color plate.
